" FUME maestras.

' Application led January 24, 1924. Serial No. 688,161.

To all whomz't may concern:

.Be it known that I, GEORGE H. BAGKMIRE,

-a citizen of the United States, residing at Third Avenue and East Street, Collegeville, in the county of Montgomery and State of Pennsylvania, have invented new and useful lniprovements in Fume Arresters, of which -the following is a specification.

a suitalile adapter which may be readily attached to different sized gas range flues whereby the fume arrester is made to fit any Agas range or other like device.

A, further object of ymy invention is to make the device in three principal sections providing for the proper itting of the joints of the sections.

A still further object of my invention is to so construct the support for an inverted glass that the cage wires may be readily secured thereto, and the tray for holding the sand or other absorbent material made a permanent part thereof to facilitate the inserton of the support and tray when it is necessary to clean the same.

Withthese ends. in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

4In order that those skilled in the art to which this invention appertains. may understand how to make and use the same, l will describe its constructionl in detail, referring by numerals to the accompanying drawings forming a part of this application in which Fig. 1, is a vertical sectional elevation of in v improvement showing the same attached over the outlet flue of a gas range.

Fig. 14, is a section at the line'14--14 of iF ig. 12.

Fig. 15, is a section at the line 15-15 of Fig. 14.

In carrying out my invention las here ernbodied, 1 represents a portion of a gas range or the like having the outlet flue 2 surrounded by a collar' over which the adapter for the 4fume arrester1 is to be placed. 4 represents the adapter which, as shown in Figs. 1 to 10, consists of a semi-spherical base having a cylindrical'tiang'e or collar 5 formedtherewith and this base is of sufficient size to be placed 'over and inclose the flue opening of any standard make of gas range: that is tosay it is of greater diameter at its base' than Vthe largest standard flue outlet of the ordinary gas range. Around the lower edge of theadapter is secured by cement or otherwise an asbestos gasket 6 so that when the adapter is placed upon the upper surface of the range as shown in Fig. 1, a packed joint will be provided.

7 represents a rod extending across the adapter, one end of which is threaded as at While the opposite end extends througli an Unthreaded opening in the boss 9; this arrangement is for convenience in assembling. Upon the rod T is slidably mounted the prongs 10, through the hubs of which are threaded the screws 11 and by means of the latter these prongs are held in any adjustment upon the rod; and between the hubs of these prongs is interposed a coil spring 12 the purpose of which latteris to force the prongs outward in tirrn Contact against' the colla r 3 when the screws 11 are released.

13 represents an extension formed with the flange and in the inner end of this extension is formed an open Slot 14 for 4the re eption of the clamp rod 153, and in practice I provide a bushing 16 preferably made of a piece of' wire so bent as to form an eye 17, through which the clamp rod may pass, and also to provide downwardly projec-ting ends 18 adapted to fit within the open end of the slot 14. By this arrangement when the clamp rod is in place the bushing will serve as n washer upon which the thumb uut 19 may bear when said nut is srewed downwardly upon the threaded end of said rod.

'lhe lower portion of the clamp rod 15 is bent at right angles and terminates in a loop 2t) which serves as a shoe to bear against the underside of the gas range top l as clearly shown in Fig. 1. Yhen this rod is in place and the thumb uut set up it will firmly hold the device iu place upon the gas range, the shoe being prevented from sli pping` backward out of engagement by the vertical portion of the rod contacting with the spring 12 or the rod 7 upon which said spring is coiled.

21 represents a reducing pipe which is tapered upward und has a straight section 22 4adapted to tit within the collar 5 and also provided with a fiauge Q3 for resting upon the upper edge of said collar to make a joint at this point 24; represents a support which is in the form 4ot' a short pipe and serves as a support for the cage 25 and an inverted glass to be placed over said tage; and for this purpose the lugs 26 are formed with the support, thro-ugh which lugs the lower ends of the wires of' the cage pass and may be secured therein by riveting or otherwise, as clearly shown in Fig. 1. Around this support is placed the tray or cup 2 whichr is preferably of sheet metal having a straight tubular section 28 fitted tightly over the lower portion ot' this support, sai-d tray being flared upward so as to make a convenient holder for any suitable absorbent materia-l, such as sand, ashes or cotton.

From the 'foregoing description the application of my invention will be obviously as follows The prongs 10 are moved toward each other as close as will be permitted bythe spring 12 and then set in position by screwing down upon the screws 11. The adapter is set over the flue opening 2 and the screws 1'1 backed off so as to permit the prongs to be forced outward by the spring 12 into firm Contact with the collar 3. This will centralize and hold the device in position temporarily until the clamp rod lis inserted within the open end slot 14 and the shoe' placed beneath the top 1 of the gas range when by screwing the thumb nut 19 downward into firm contact with the bushing 16 the device will be permanently locked in place. The tray 2'( may be then filled with sand, or other suitable material, and a glass, such as a drinking glass, inverted over the cage 2.3 and caused to rest upon the lugs 26 of the support Qt; it being undeistood that a suitable absorbent material such as raw cotton is placed upon the Wires of the cage for arresting tertain objectionable matter which would otherwise pass off as fumes from the gas range.

The form of -my invention above described is especially designed for making the adapter, reducing pipe and support ot' cast iron While the modified form shown in Figs. 10 and 11 is especially adapted for making these parts of sheet metal, the construction being as follows The adapter 44 in this modification instead of bein semi-spherical has its lower portion of cylindrical shape while the upper portion thereof is in the general form of a truncated cone with which is formed the short pipe 55. The lower end of the reducing pipe 121 is adapted to fit over the short pipe while the upperV portion of this reducing pipe serves to receive and support the cage 120. p

A bead 56 is preferably formed around the reducing pipe in order that the tubular section 2813i the tray 2, when passed over the upper portion of the reducing pipe, may be limited in its downward movement by said head thus t'aeilitating the assembling of the device.

113 represents a bracket which serves the same purpose as the extension 13 before described through which the rod 15 passes for clamping the device in place. In this moditication 7i' represents the cmss nod which projects through the walls of .the adapter and has its ends headed up after the manner of rivets as indicated at 57.

Instead of utilizing two sliding prongs as in the previously described form of construction I here utilize only one of such sliding prongs designated as 100, and in the place of the second sliding prong I use a stationary prong 101, the shank of which latter is riveted to the wall of the adapter as indicated at 102, and in practice the prong 10() is .attached upon the rod 77 in a position relative to the prong 101 no correspond to the size of the line opening so that these two prongs may be passed into said flue opening thus dc- Ell) lermining the position of the adapter upon the gas range and preventing any sidewise movement thereof. 'lhe clamp rod 15v serves to hold the device againstvertical displacement in the same manner 11s-before described.

The cage 120 adapted to this modified construction ronsists of the wires 125'rwhicli cross each other at the top and extend downward at right angles and are coiled around the ring 126 thereafter estending horizontally outward forming the supports 124 their ends being clamped around the ring 127. This makes it possible to readily apply the cage to the device or remove the same therefrom thus facilitating the shipping and as- 'sembling of the device.

In the formation illustrated in Figs.12 to 15 inclusive, 144 represents the adapter including a flat base 145 having a sheetof asbestos 146 disposed across its under face and provided with an upwardly projecting collar or flange 147. These parts are preferably of oval shape although I am not limited to any specific configuration. An extension 148 is formed with the collar 147 similar to the extension 13 and for the same purpose.

A rod 149 extends across the adapter with its end fixed in the collar 147 and on this rod, preferably midway its length, is secured a pendant 150 having an elongated opening 151 therethrough in which are slidably mounted the shanks 152 of the gripping prongs 153 and said Shanks are preferably of polygonal cross section to prevent rotation of the gripping prongs. In the lower end of the pendant is threaded a screw 154 which projects into the opening 151 for engagement with the Shanks of the gripping prongs to force them together and against the top wall of the elongated opening to bind them in any adjusted position as will be obvious.

In the use of this form of the device the screw 154 is released from the Shanks of the gripping prongs 158 and the latter adjusted so that their outer free ends engage the inner surface of the gas range collar 3 after which the screw 154 may again be screwed home to hold the prongs in their adjusted positions. The coaction of the gripping prongs with the range collar will properly position the adapter after which the clamp rod may be attached in the same manner as before described and the fume arrester then mounted on the adapter.

Of course I do notwish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departingr from the spirit of my invention.

Having thus fully described mv invention, what I claim as new and useful is 1 A fume arrester comprising an adapter of sufficient dimensions to set over and inclose an outletfflue of a gas range, means for locating and temporarily ho ding the device an place `Vupon the gas range, and means forclamping the device in final position.l`
